Put enough tubes in series, and you can get any voltage you want. But watch it when one goes!
By the way, Eimac has a 500,000 watt tube that you can go to if the 150,000 watt one isn't heavy duty enough.
Actually, you could have true direct drive. You place some electret material over your ear drums, but insulated from the skin. You subsequently sit between some big stators driven in push-pull. Your ear drums should vibrate to the signal. No headphones, no speakers!
